if im understanding what you are saying, use the vtec controller + signal to trigger a relay and then have this relay activate ground on the vvl solenoid, while having the vvl solenoid connected to battery 12 volts on the other wire.

Relay: one side connected to ground, the + side waiting the signal from the vtec controller. The magnet side, one terminal directly to ground, the other side to the vvl solenoid so ground circuit will close when the vtec controller sends 12V to the relay.

thank you

I am understand this.

but I'm not understand, How to wire input side signal from ECU to VTEC CONTROLLER ??

your better off with a greedy mss.tgis will save you time.in trigger vvl correctly.because unlike honduhh we have to trigger two silinoids n honduhh only triggers one.we activate on negitive and honduhh activates on possitive..

That is one disadvantage but if he already has bought that controller, he can add the relays and use it still.

And since you are saying Greddy MSS, tell me where to buy a new one now? It has been discontinued.
